Documented stone-softening and artificial-stone knowledge has been lost from mainstream memory repeatedly across eras — the 19th-century artificial-stone industry (Coade stone, Pulhamite, Belgian patents), indigenous softening-plant traditions, conquistador-era chronicles, and traveler accounts each record working knowledge later forgotten.

Evidence
No evidence records attached yet — this claim is held on its source anchor alone: the ledger knows where the proposition is stated and has admitted no observation behind it. A source is not evidence.
an honest empty state
This claim is in the ledger but not in the current edition's featured set. Nothing here has been assessed — that absence is information, not an oversight.
Still missing: plain-language gloss, credibility assessment, diagnosticity assessment, strongest objection, what would change our mind. A claim gains them when an edition features it and the edition's adopted assessment supplies the full treatment — a decision the panel reviews, not a field anyone flips.
